Abstract: A primer feed mechanism device for use with a carrier assembly of a large liber cannon. The device includes a body for mounting the device to the carrier assembly so as to interface with the carrier assembly to position the device on one side of the breech of the cannon. It further includes a body cam surface and a tray assembly which provides a cam path for movement thereof. The tray assembly includes slide rails for engagement with the body and an injector arm which is operably controlled by the body cam surface. Also included is a control arm assembly housed in the carrier assembly for engaging the cam path at one end and for engaging the tray assembly at its other end. The control arm assembly is adapted to move the tray assembly from a first ready-to-fire position to a primer extract/inject position, the movement being controlled from the control arm assembly and the breech mechanism of the cannon.
